The four I-model for scaffolding the professional development of experienced teachers in the use of virtual learning environments for classroom teaching.

Models of professional development for teachers have been criticized for not being embedded in the context in which teachers are familiar, namely their own classrooms. This paper discusses an adapted-Continuous Practice Improvement model, which qualitative findings indicate was effective in facilitating the transfer of creative and innovative teaching approaches from the expert or Resident Teacher’s school to the novice or Visiting Teachers’ classrooms over the duration of the project. The cultural shift needed to embed and extend the use of online teaching across the school was achieved through the positive support and commitment of the principals in the Visiting Teachers’ schools, combined with the success of the professional development activities offered by the Visiting Teachers to their school-based colleagues.

Christian Gottlob Neefe and the Bonn National Theatre, with New Light on the Beethoven Family

When the Bonn stage was closed after the death of Elector Max Friedrich in 1784, the director of its theatre company, Gustav Friedrich Wilhelm Großmann, decided to leave the city to further his career elsewhere in the Rhinelands. During the next few years, he was kept informed about developments in Bonn by two of his erstwhile colleagues, Christian Gottlob Neefe and Nikolaus Simrock, whose correspondence paints a vivid picture of musical life in the city during the later 1780s. The new Elector, Maximilian Franz, permitted a visiting troupe to perform during Carnival each year, but repeatedly delayed the decision to re-establish a resident troupe. In 1787 Christoph Brandt, a singer in the Bonn Hofkapelle, attempted a home-grown initiative, perhaps to test the market for a new permanent company. Although this failed almost immediately, a single, well-attended public rehearsal of Monsigny’s Le Déserteur was given, in which Johann van Beethoven made what was probably his last stage appearance. In a letter dated 14 May 1787, Simrock rated his performance ‘zimlich gut’. In the event, a new Bonn troupe was not recruited until 1789, when it featured the young singer Magdalena Willmann. Neefe and his musical colleagues were relieved finally to be able to resume their theatrical careers.

Moral distress experienced by health care professionals who provide home-based palliative care

Health care providers regularly encounter situations of moral conflict and distress in their practice. Moral distress may result in unfavorable outcomes for both health care providers and those in their care. The purpose of this study was to examine the experience of moral distress from a broad range of health care occupations that provide home-based palliative care as the initial step of addressing the issue. A critical incident approach was used in qualitative interviews to elicit the experiences on moral distress from 18 health care providers drawn from five home visiting organizations in south central Ontario, Canada. Most participants described at least two critical incidents in their interview generating a total of 47 critical incidents. Analyses of the critical incidents revealed 11 issues that triggered moral distress which clustered into three themes, (a) the role of informal caregivers, b) challenging clinical situations and (c) service delivery issues. The findings suggest that the training and practice environments for health care providers need to be designed to recognize the moral challenges related to day-to-day practice.

Reproductive biomass in Holcus lanatus clones that differ in their phosphate uptake kinetics and mycorrhizal colonization

In normal populations of the common grass Holcus lanatus there is a polymorphism for arsenate resistance, manifested as suppressed phosphate uptake (SPU), and controlled by a major gene with dominant expression. A natural population of SPU plants had greater arbuscular-mycorrhizal colonization than wild type, nonSPU plants. It was hypothesized that, in order to survive alongside plants with a normal rate of phosphate (P) uptake, SPU plants would be more dependent on mycorrhizal associations. We performed an experiment using plants with SPU phenotypes from both arsenate mine spoils and uncontaminated soils, as well as plants with a nonSPU phenotype. They were grown with and without a mycorrhizal inoculum and added N, which altered plant P requirements. We showed that grasses with SPU phenotypes accumulated more shoot P than nonSPU plants, the opposite of the expected result. SPY plants also produced considerably more flower panicles, and had greater shoot and root biomass. The persistence of SPU phenotypes in normal populations is not necessarily related to mycorrhizal colonization as there were no differences in percentage AM colonization between the phenotypes. Being mycorrhizal reduced flower biomass production, as mycorrhizal SPU plants had lower shoot P concentrations and produced fewer flower panicles than non-mycorrhizal, nonSPU plants. We now hypothesize that the SPU phenotype is brought about by a genotype that results in increased accumulation of P in shoots, and that suppression of the rate of uptake is a consequence of this high shoot P concentration, operating by means of a homeostatic feedback mechanism. We also postulate that increased flower production is linked to a high shoot P concentration. SPU plants thus allocate more resources into seed production, leading to a higher frequency of SPU genes. Increased reproductive allocation reduces vegetative allocation and may affect competitive ability and hence survival, explaining the maintenance of the polymorphism. As mycorrhizal SPU plants behave more like nonSPU plants, AM colonization itself could play a major part in the maintenance of the SPU polymorphism.

Organization specific predictors of job satisfaction: findings from a Canadian multi-site quality of work life cross-sectional survey

Background: Organizational features can affect how staff view their quality of work life. Determining staff perceptions about quality of work life is an important consideration for employers interested in improving employee job satisfaction. The purpose of this study was to identify organization specific predictors of job satisfaction within a health care system that consisted of six independent health care organizations.

Methods: 5,486 full, part and causal time (non-physician) staff on active payroll within six organizations (2 community hospitals, 1 community hospital/long-term care facility, 1 long-term care facility, 1 tertiary care/community health centre, and 1 visiting nursing agency) located in five communities in Central West Ontario, Canada were asked to complete a 65-item quality of work life survey. The self-administered questionnaires collected staff perceptions of: co-worker and supervisor support; teamwork and communication; job demands and decision authority; organization characteristics; patient/resident care; compensation and benefits; staff training and development; and impressions of the organization. Socio-demographic data were also collected.

Results: Depending on the organization, between 15 and 30 (of the 40 potential predictor) variables were found to be statistically associated with job satisfaction (univariate analyses). Logistic regression analyses identified the best predictors of job satisfaction and these are presented for each of the six organizations and for all organizations combined.

Conclusions: The findings indicate that job satisfaction is a multidimensional construct and although there appear to be some commonalities across organizations, some predictors of job satisfaction appear to be organization and context specific.

Hormone therapy and intraocular pressure in nonglaucomatous eyes

Objective: The influence of sex hormones on intraocular pressure (IOP) has been the focus of recent debate. Previous studies investigating the effects of hormone therapy (HT) on IOP in postmenopausal women have produced conflicting results but have been limited by small numbers of participants. The aim of our study was to compare IOP in women without glaucoma taking HT with those not taking HT. Methods: A prospective cross-sectional study of postmenopausal women visiting a single ophthalmic medical practitioner was conducted. All women with a history of intraocular disease, a family history of glaucoma, or refractive error exceeding ±5 diopters were excluded. Applanation tonometry was used to measure IOP, and participants were then asked if they were current HT users. Results: A total of 263 participants were recruited, of whom 91 reported current use of HT; 172 had never used HT. Within the HT group, 33 were taking an estrogen-therapy and 58 were taking a estrogen-progesterone therapy. Mean IOP in the HT group was significantly lower than that in the non-HT group; the mean difference was 1.41 mm Hg (P <0.001). This difference remained statistically significant after statistical correction for age, use of systemic ß-blockers, and time of IOP measurement. There was no significant difference in mean IOP between women taking combined versus those taking estrogen-only preparations. Conclusions: Our study showed that IOP was significantly lower in women taking HT than in those who had never taken HT, even after removing other possible influences on IOP. The IOP-lowering effect of HT deserves further investigation to explore whether it may represent a possible new therapeutic modality for glaucoma. © 2010 by The North American Menopause Society.

Transfer of amiprophosmethyl resistance from a Nicotiana plumbaginifolia mutant by somatic hybridisation

Transfer of resistance to the phosphorothioamidate herbicide, amiprophosmethyl (APM), from the P-tubulin mutant of Nicotiana plumbaginifolia to the interspecific N, plumbaginifolia (+) N, sylvestris is and to the intertribal N, plumbaginifolia (+) Atropa belladonna somatic hybrids has been demonstrated. Transfer to the recipient species was accomplished by: (1) symmetric hybridisation and (2) asymmetric hybridisation using gamma-irradiation of donor protoplasts. Cytogenetic analysis confirmed the hybrid origin of the hybrids obtained. It was established that most of them typically inherited no more than three donor chromosomes, although it was possible to obtain symmetric hybrids in the case of symmetric fusion. Immunofluorescent microscopy analysis has shown that protoplasts of the mutant, and of the N. plumbagini-folia (+) N. sylvestris and N. plumbaginifolia (+) A. belladonna hybrids, retained the normal structure of interphase microtubule (MT) arrays and mitotic figures after treatment with 5 mu M APM, whereas MTs of protoplasts of the recipients were destroyed under these conditions. It was also shown that hybrid clones contained an altered beta-tubulin isoform originating from the N. plumbaginifolia mutant. The selected hybrid clones were characterised by cross-resistance to trifluralin, a dinitroaniline herbicide with the same mode of anti-MT action. Some of the somatic hybrids which could flower were fertile. It was established that seeds of some fertile hybrids were able to germinate in the presence of 5 mu M APM. The results obtained thus support the conclusion that the technique of somatic hybridisation, especially asymmetric fusion, can be used to transfer APM resistance from the N. plumbaginifolia mutant to different (related and remote) plant species of the Solanaceae, including important crops.

International differences in sport medicine access and clinical management

I undertook the 2012 ECOSEP travelling fellowship, sponsored by Bauerfeind, between May and August 2012, which involved visiting 5 European sport medicine centres and spending approximately one week in each centre. The 5 centres included: National Track and Field Centre, SEGAS, Thessaloniki, Greece; Professional School in Sport & Exercise Medicine, University of Barcelona, Spain; Sport Medicine Frankfurt Institute, Germany; Isokinetic Medical Group, FIFA Medical Centre of Excellence, Bologna, Italy, and Centre for Sports and Exercise Medicine, Barts and the London School of Medicine and Dentistry, Mile End Hospital, England. Throughout the fellowship, the clinical cases which were routinely encountered were documented. The following sections detail my experiences throughout the fellowship, the sports of the athletes and the injuries which were treated at each of the sport medicine centres during the fellowship visit and the different forms of management employed. © 2012, CIC Edizioni Internazionali

Neonatal intensive care and late preterm infants:Health and family functioning at three years

Background: Late preterm infants (LPIs), born at 34 + 0 to 36 + 6 weeks of gestation contribute a significant proportion of all neonatal intensive care (NIC) admissions and are regarded as being at risk of adverse outcomes compared to term-born infants.

Aim: To explore the health outcomes and family functioning of LPIs who required neonatal intensive care, at three years of age.

Study design and subjects: This cohort study included 225 children born late preterm, between 1 January and 31 December 2006 in Northern Ireland. Children admitted for NIC (study group, n = 103) were compared with children who did not require NIC or who required special care only for up to three days (comparison group, n = 122).

Outcome measures
Health outcomes were measured using the Health Status Questionnaire, health service usage by parent report and family functioning using the PedsQL™ Family Impact Module.

Results: LPIs who required NIC revealed similar health outcomes at three years in comparison to those who did not. Despite this, more parents of LPIs who required NIC reported visiting their GP and medical specialists during their child's third year of life. Differences in family functioning were also observed with mothers of LPIs who required NIC reporting, significantly lower levels of social and physical functioning, increased difficulties with communication and increased levels of worry.

Conclusions: LPIs were observed to have similar health outcomes at three years of age regardless of NIC requirement. The increase in GP and medical specialist visits and family functioning difficulties observed among those infants who required NIC merits further investigation.

Optimal Front Page Advertising

We consider a model of an on-line software market, where an intermediary distributes products from sellers to buyers. When products of sellers are vertically differentiated, an intermediary, earning a proportion of sales, has an incentive to hide the worse product on the second page, and only keep the better product on the front page: that weakens the competition, allowing the seller with the better product to charge a higher price. With heterogeneous visiting costs to the second page, the platform's revenue might improve, but the outcome will become socially suboptimal.

Developing a Reporting Guideline for Social and Psychological Intervention Trials

Social and psychological interventions are often complex. Understanding randomized controlled trials (RCTs) of these complex interventions requires a detailed description of the interventions tested and the methods used to evaluate them; however, RCT reports often omit, or inadequately report, this information. Incomplete and inaccurate reporting hinders the optimal use of research, wastes resources, and fails to meet ethical obligations to research participants and consumers. In this article, we explain how reporting guidelines have improved the quality of reports in medicine and describe the ongoing development of a new reporting guideline for RCTs: Consolidated Standards of Reporting Trials-SPI (an extension for social and psychological interventions). We invite readers to participate in the project by visiting our website, in order to help us reach the best-informed consensus on these guidelines (http://tinyurl.com/CONSORT-study).
